req.session.flash = { } 不工作 sails.js
req.session.flash = { } not working sails.js
我真的是 sails.js 的新手,目前我正在使用 sails 1.0。当我尝试验证我的注册页面时遇到问题,一旦表单无效,错误消息就会按预期显示在表单上方,但是当我进行刷新时它仍然存在。除此之外一切都还好。
路由是手动完成的,我认为问题出在 api/controllers/UsersController.js
中的 req.session.flash = {};
这不是空对象!!
api/controllers/UsersControllers.js
module.exports = {
signup:function(req,res,next){
res.locals.flash = _.clone(req.session.flash);
res.view('pages/signup');
req.session.flash = {};
},
create:function(req,res,next){
var values = req.allParams();
Users.create(values).exec(function(err,user){
// if there's an error
if(err){
console.log(err);
req.session.flash = {
err: err
}
// if error redirect back to signup page
return res.redirect('/users/signup');
}
// After successfully creating the user
// redirect to the show action
res.view('pages/create');
req.session.flash = {};
});
}
};

如果我的记忆没有出卖我,您必须在发送回复之前对您的 session
object 进行任何更改。在你的 api/controllers/UsersControllers.js
中尝试交换这两行:
res.view('pages/create');
req.session.flash = {};
应该是:
req.session.flash = {};
res.view('pages/create');
阅读有关会议的更多信息here。最重要的是:
The property will not be stored in the session store nor available to
other requests until the response is sent.
